hi,
i am not sure, if this is the right place for my problem, because i
think it could be a pure python email problem.

i try to send pdf files stored in archetypes file fields via python
email module. the resulting email looks fine, but if i open one of
these pdf attachment in my thunderbird, it is somehow corrupted -
it opens in acrobat but only shows white/empty space. i use
plone 3.3.1 on RHEL.

first i thought that the reason for this corruption could be
caused by incorrect file data. data in archetypes file field is
wrapped in acquisition and this pdata thing. but i think i solved
that by using: filedata = str(aq_base(filedata)).

i tried it with both original ATFile and with custom filefields.

------------------------------------------------------------------------------

# 1) just return pdf data to browser for testing purposes

from Acquisition import aq_base

archobj = ploneroot['testfile.pdf']     # later i use a sequence of
fieldid = 'file'                        # (archetypesobj,filefieldid) tuples

filefield = archobj.getField(fieldid)
mimetype = filefield.getContentType(archobj)
filename = filefield.getFilename(archobj)
filedata = filefield.getRaw(archobj).data
filedata = str(aq_base(filedata))
self.REQUEST.RESPONSE.setHeader('Content-Type','application/pdf')
return filedata

# result: pdf opens in acrobat, everything looks wonderful

------------------------------------------------------------------------------

# 2) try to email this (plain text mail with attachment):

from email.Header import make_header
from email.MIMEMessage import Message
from email.MIMEBase import MIMEBase
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
import smtplib

archobj = ploneroot['testfile.pdf']
fieldid = 'file'

messagetext = 'Test text'
subject = 'Test Subject'
mfrom = '[hidden email]'
mto = '[hidden email]'

# create message

msg = MIMEMultipart('related')
msg.attach(MIMEText(messagetext, 'plain', 'utf-8'))
msg.preamble = subject
subject = unicode(subject, 'utf-8')
msg['Subject'] = str(make_header([(subject, 'utf-8')]))
msg['Subject'] = subject
msg['From'] = mfrom
msg['To'] = mto

# attach pdf

filefield = archobj.getField(fieldid)
mimetype = filefield.getContentType(archobj)
filename = filefield.getFilename(archobj)
filedata = filefield.getRaw(archobj).data
filedata = str(aq_base(filedata))
maintype, subtype = mimetype.split('/', 1)
subpart = MIMEBase(maintype, subtype)
subpart.set_payload(filedata)
subpart.add_header('Content-Disposition', 'attachment', filename=filename)
msg.attach(subpart)

# send msg

server = smtplib.SMTP('mx.y.at')
server.sendmail(mfrom, mto, msg.as_string())

# result as explained above: the attachment file is somehow corrupted,
# the email message source looks like:

hi,
ok, solved that now. what a mess: when i had solved the problem with
str(aq_base(filedata)) to get the correct file data i inserted another
bug, which i didn´t have before. the correct code to mail archetypes
filefield pdfs with python email:

encoders.encode_base64(subpart) # was missing

----------------------------------------------------------

from email.Header import make_header
from email.MIMEMessage import Message
from email.MIMEBase import MIMEBase
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
import smtplib

archobj = ploneroot['testfile.pdf']
fieldid = 'file'

messagetext = 'Test text'
subject = 'Test Subject'
mfrom = '[hidden email]'
mto = '[hidden email]'

# create message

msg = MIMEMultipart('related')
msg.attach(MIMEText(messagetext, 'plain', 'utf-8'))
msg.preamble = subject
subject = unicode(subject, 'utf-8')
msg['Subject'] = str(make_header([(subject, 'utf-8')]))
msg['Subject'] = subject
msg['From'] = mfrom
msg['To'] = mto

# attach pdf

filefield = archobj.getField(fieldid)
mimetype = filefield.getContentType(archobj)
filename = filefield.getFilename(archobj)
filedata = filefield.getRaw(archobj).data
filedata = str(aq_base(filedata))
maintype, subtype = mimetype.split('/', 1)
subpart = MIMEBase(maintype, subtype)
subpart.set_payload(filedata)
encoders.encode_base64(subpart)
subpart.add_header('Content-Disposition', 'attachment', filename=filename)
msg.attach(subpart)

# send msg

server = smtplib.SMTP('mx.y.at')
server.sendmail(mfrom, mto, msg.as_string())
